Galatasaray striker Victor Osimhen will undergo a late fitness test to determine his availability for Monday’s highly anticipated Istanbul derby against arch-rivals Fenerbahce.

The Nigerian forward has been sidelined for Galatasaray’s last two matches due to injury. According to Turkish outlet Sabah, the club is eager to have him back, especially after their disappointing 1–0 defeat to Union St. Gilloise in the UEFA Champions League on Tuesday.

Okan Buruk’s men struggled to create meaningful attacking threats in Osimhen’s absence, a reminder of just how vital he has become to the Turkish giants’ frontline.

Osimhen has enjoyed a strong start to life in Istanbul, recording nine goals in 12 appearances across all competitions this season. His return could provide a massive boost as Galatasaray—who currently sit atop the Super Lig table with 32 points—prepare for a derby that could reshape the title race. Fenerbahce trail closely with 31 points, making Monday’s showdown one of the biggest fixtures of the season.

Opinion: Derby Without Osimhen? Galatasaray Can’t Afford It

If there’s one truth in football, it’s this: big players decide big games. And when it comes to Galatasaray, Victor Osimhen is that player.

His absence in the Champions League loss was glaring. Galatasaray looked blunt, predictable, and lacked the cutting edge that Osimhen naturally brings. His movement, aggression, and ability to turn half-chances into goals make him the heartbeat of their attack. Without him, Galatasaray are simply not the same force.

The Istanbul derby is not just another match—it’s a battle of pride, bragging rights, and season-defining momentum. With only one point separating the two clubs, the stakes could not be higher. Fenerbahce smell blood. Galatasaray cannot afford to hand them an advantage by going into the match without their most dangerous weapon.

Even if Osimhen is not 100% fit, his presence alone lifts the team, intimidates defenders, and energizes the fans. A derby atmosphere feeds off star power, and Osimhen’s name carries weight.

If he plays, Galatasaray enter the derby with belief.
If he doesn’t, it becomes a completely different game—one where Fenerbahce suddenly have the upper hand.

Either way, all eyes will be on the team sheet come Monday.
